Study Notes
Information Systems
- Composed of five components: people, procedures, software, hardware, and data.
- People are the end users who interact with the system to enhance productivity.
- Procedures include rules and guidelines for using software and hardware effectively.
- Software refers to the programs that convert raw data into meaningful information.
- Hardware encompasses the physical devices used in the information system.
- Data consists of unprocessed facts awaiting processing for usability.
Data vs. Information
- Data consists of raw, unprocessed facts; for example, customer purchase records.
- Information is data that has been processed and organized to provide meaning.
Operating System
- An operating system is essential software that manages computer hardware and software resources.
- It facilitates communication between applications and the hardware.
- Examples include Windows, macOS, Linux, and Unix.
Application Software
- Application software serves specific user needs and tasks, often termed "end-user" software.
- Common examples: word processing (MS Word), spreadsheets (Excel), databases (MS Access), and presentations (PowerPoint).
Types of Application Software
- Basic applications are essential for everyday computer usage.
- Specialized applications cater to particular tasks in fields like multimedia and education.
Input Devices
- Input devices allow users to interact with computers by converting user actions into a form the computer can process.
- Common examples include keyboards and mice. Other devices include scanners, microphones, and digital cameras.
Output Devices
- Common output devices include monitors, printers, speakers, plotters, and projection units that display or produce results from computer processes.
Storage Types
- Primary storage (e.g., RAM) is temporary and loses data when power is off.
- Secondary storage (e.g., hard drives) retains data even when power is turned off, providing long-term data storage.
Internet vs. World Wide Web
- The Internet is a vast network of interconnected computers and devices, forming the foundation for data communication.
- The World Wide Web is a collection of multimedia resources accessible over the Internet, representing one of many Internet applications.
Types of Computers
- Supercomputers are the most powerful computers used for complex calculations and large-scale processing requirements.
- Mainframes offer high processing speeds and storage but are less powerful than supercomputers.
- Minicomputers are midrange systems suited for specific tasks, typically used by medium-sized businesses.
- Microcomputers, despite being the least powerful, are the most widely used type of computer for personal and small business applications.
URL Components
- Uniform Resource Locator (URL) parts include the protocol, domain name, and file path, defining the resource location on the Internet.
